Abstract: A control system is provided. The control system includes a turbine controller that is configured to generate at least a first signal that is representative of pitch control commands for a plurality of turbine blades and a second signal that is representative of the pitch control commands for the turbine blades. A first pitch controller is coupled to the turbine controller, wherein the first pitch controller is configured to receive the first signal and to implement the pitch control commands for each of the turbine blades in response to receiving the first signal. A second pitch controller is coupled to the turbine controller and to the first pitch controller, wherein the second pitch controller is configured to receive the second signal and to implement the pitch control commands to each of the turbine blades when the first pitch controller is unable to implement the pitch control commands.
